Tascalate Concurrent 0.8.0

The following changes are made since 0.7.1

1. Fixed exceptional completion handling in Promise.orTimeout and Promise.onTimeout operations
2. The artifact was renamed to align naming across other Tascalate projects

IMPORTANT!
From version 0.8.0 please use the following artifact name:

<dependency>
    <groupId>net.tascalate</groupId>
    <artifactId>net.tascalate.concurrent</artifactId>
    <version>0.8.0</version>
</dependency>

The old naming was:

    <version>0.7.1</version>
